In the X11R5 (MIT) release there is a bug in which the string to set the
font size in a Xterm has the font size it selects set to 1pt the xterm dumps
core and exits. (this string can be written to the screen)

As most default setups usually have the Xterm -C as the last command in the
.xinitrc file the net effect is to blow all the 1st years off your server.

Of course having a sym link in your file space along the lines of:
core -> /dev/rsd0a and as xterm runs as root, is also a good way of
breaking your machine...

I've never tried this (Gee! I wonder why ;) - try nuking some other root
owned file.

Disclaimer: this is not a bug in SunOS/Openwin
